In the beginning, it reminded me of Dark City.
In the middle, it reminded me of Alien.
In the end, it reminded me of Matrix.

Case in point, try to see this movie - it's great sci! The end is the only part that kind of plods along and could have used some refinement. Don't let the German language/subtitles scare you off. It's up to par with Europa Report and better than any recent Hollywood schlock.
